I haven't bothered to post this because I felt it so trivial, but I recently decided "what the heck"

I have all custom music...game, events...everything. Recently, I've noticed my music not "switching back". For example, say I'm talking to the Torians. My Torian theme music kicks in and plays. But when I click 'done' and the trade screen goes away, the Torian music continues playing instead of kicking over to the "game" music. Then the only time it changes is when I talk to another race, I go to war, etc. but they seem to play on endlessly.
I've seen other posts stating that the game music rarely changes, but this is something I'v eonly recently experienced. I mean, I really don't like hearing Torian trade screen music over, and over, and over, and over...
This started happening when I updated TotA a couple of betas ago. However, I had not updated DA either (to 1.80g) and kept getting little reminder messages saying so. I never bothered until just recently because the TotA beta didn't seem to suffer any ill effect. But this music issue of mine seems to have started about the time I updated DA to its most recent version.
OK, this is a long post for a trivial matter, but I was just curious...and I did spend a bit of time edting and replacing all this music. Should I just delete DA all together and re-download it again?
